Louis van Gaal did not hold back when asked why he replaced youngster Paddy McNair before the half time interval during Manchester United's 2-1 win over Southampton.
The Old Trafford boss said McNair was hauled off before the break because he 'had no confidence and had given away three chances.'
Van Gaal went on to describe the United youngster's performance as "disappointing for me and for him."
McNair was replaced just before the break by Ander Herrera, with Michael Carrick dropping back from midfield into central defence.
The substitution was actually United's second of the first-half, after Van Gaal was forced to replace Chris Smalling with Jonny Evans after Smalling picked up an injury.
Manchester United claimed all three points although Van Gaal did go on to admit that 'Southampton were the better side and we [United] were very lucky [to win].

A brace from Robin van Persie did the damage, the Dutchman scoring either side of a Graziano Pelle equaliser.
United only had three shots during the match, all by Van Persie, but the Netherlands international hit the target with two of them and that was all that was necessary for United to claim the points and leapfrog Southampton and West Ham United into third place in the Premier League table.
Next up for Van Gaal's side is the visit of Liverpool, with Brendan Rodgers's side looking to end United's streak of five consecutive wins in all competitions.
They've not been playing well, but it's the results that count.
